摘要:This paper discusses the reasonable collocation of natural casings. Through the analysis and research of the problems, the optimal model of the bundle number of assembled products is established. For this multi-objective optimization problem, the finished products are sorted according to the length from long to short, and then the method of hierarchical optimization algorithm is used to solve the problem. Finally, the empirical analysis of the given actual data is carried out. It provides an important idea for the formulation of the collocation scheme, and the solution of this problem can be extended to other aspects of production.
